A non-Bethe-ansatz solution of the strong coupling t-V model with twisted-boundary conditions

We present the solution of the one-dimensional t-V model with twisted-bound ary conditions in the strong coupling limit, t much less than V and show th at this model can be mapped onto the strong coupling Hubbard chain threaded by a fictitious flux proportional to the total momentum of the charge carr iers. The high-energy eigenstates are characterized by a factorization of d egrees of freedom associated with configurations of soliton and anti-solito n domains and degrees of freedom associated with the movement of ;"holes" t hrough these domains. The transport properties of this model are studied. ( C) 2001 Elsevier Science B.V. All rights reserved.
